Successfully Achieving and Maintaining Euglycemia During Pregnancy for Type 2 Diabetes Through Technology and Coaching
What this study is about
The ACHIEVE RCT will measure the effect of the intervention (mHealth app with CGM, provider dashboard, and care team coaching) compared to current standard care (prenatal visits, self-monitored blood glucose, and certified diabetes care and education specialist) on achieving glycemic control (hemoglobin A1c \<6.5% in the third trimester).
View original scientific description
The ACHIEVE RCT will measure the effect of the intervention (mHealth app with CGM, provider dashboard, and care team coaching) compared to current standard care (prenatal visits, self-monitored blood glucose, and certified diabetes care and education specialist) on achieving glycemic control (hemoglobin A1c \<6.5% in the third trimester). We hypothesize a 25% absolute increase in the proportion of participants in the intervention group who will meet the target hemoglobin A1c \<6.
Interventions
DEVICE
DEXCOM G7 PRO Continuous Glucose Monitor
Participants in the intervention arm will be provided with DEXCOM® G7 PRO CGM sensors and transmitters. The Dexcom G7 CGM system is accurate and safe in pregnant individuals with diabetes. Participants will be taught how to place and remove CGM sensors by a trained research nurse, and will be given sensors to change themselves at home every 10 days. Of note, the DEXCOM® G7 PRO can be applied as a patch on the abdomen, arm, or upper buttocks, is well-tolerated in pregnancy, and does not require calibration. Our mHealth app will allow for wireless synchronization with the CGM sensor so that data are seamlessly reported back to the healthcare team.
DEVICE
Patient mHealth app linked to a provider dashboard
The mHealth app is based on our team's prototype intervention developed at our study site. The mHealth app provides diverse functions, including education, reminders, care goals, care pathway recommendations, CGM data and PROs reporting and monitoring, messaging and video conferencing, and a calendar function. Content is based on clinical guidelines for diabetes in pregnancy. Participants will be directed to appropriate resources and online learning to help them navigate the app and its resources. PROs in the mHealth app will be embedded to address health and social needs, and rule-based algorithms will provide tailored care goals, show care pathways, and establish the frequency of elicited PROs.
BEHAVIORAL
Care team coaching for medical and social needs (HUB)
Participants will be screened at enrollment and throughout the intervention for social needs using a survey adapted from validated instruments, such as the Accountable Health Communities Health-Related Social Needs Screening Tool. The care team will refer participants with affirmative responses to the HUB through the provider dashboard to address social needs (e.g., food insecurity, housing, employment). HUB community health workers will perform comprehensive social needs assessments and connect participants to community resources through "care pathways," a defined action plan addressing patient needs which is recorded and tracked.
DEVICE
Provider dashboard
The ACHIEVE intervention will include a bi-directional dashboard that displays information about individuals, including priority care goals and pathways, and recommendations generated via PROMPT. Healthcare team members can access the dashboard embedded within a portal to modify or update information and close the loop on participant tasks. The dashboard will present recommendations for participant goals and pathways provided by the PROMPT algorithms. Providers can use these recommendations or manually select ones for the participant. Providers can sequence goals and pathways by level of complexity. Both the HUB and the healthcare team can perform ongoing assessments of HUB pathway selections and assess recurring needs through the provider dashboard.
Primary outcome measures
The primary clinical outcome is the proportion of participants with an A1c <6.5% in the third trimester before delivery
Time frame: From ≤20 weeks of gestation to delivery, an average of 5 months
A1c is a blood test that represents the average glucose over the previous three months. Our outcome threshold is slightly higher than the target of \<6.0 recently recommended by ADA because: 1) our target population of pregnant individuals includes those with poor glycemic control at enrollment, 2) an aggressive target \<6% can result in frequent episodes of hypoglycemia, of particular concern for participants in the standard care arm without CGM, and 3) the frequency of adverse neonatal outcomes are similar with third trimester A1c 6-6.4% vs. \<6%. A1c will be assessed once per trimester, consistent with ADA and ACOG guidelines for T2D management in pregnancy, and at delivery. For participants with \>1 value in the third trimester, the value closest to delivery will be used. A standard assay will be used for HbA1c. We will evaluate HbA1c as an absolute percentage of total hemoglobin using reference standards per the Diabetes Control and Complications Trial Reference Method.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- pregnant individuals age ≥18 years;
- ≤20 weeks of gestation (specifically, \<20+6 weeks);
- diagnosis of pregestational T2D and A1c ≥6.5% at the time of study enrollment;
- Medicaid insurance;
- English or Spanish speaking;
- cognitively able to complete the study requirements;
- consent to all study activities;
- accessible for participation in study activities;
- use a smartphone with internet access; Participants must also consent to the study team abstracting information from their electronic health records (EHRs), using CGM for glucose monitoring if randomized to the intervention group, tracking the participants' clinic, hospital, and emergency room visits during the study period, as well as tracking the number of times the participants use the ACHIEVE mobile health (mHealth) application (app), including what activities are used in the mobile application (e.g., recording blood glucose, scheduling appointments, messaging their healthcare providers, accessing educational resources).

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
